• Rock cycle


  1. Weathering

  2. Erosion

  3. Sediment formation

  4. Deposition

  5. Compaction

  6. Cementation

  7. Metamorphism

  8. Melting

  9. Igneous rock formation
• Rock types


  • Igneous
  • Metamorphic
  • Sedimentary
• Sediment formation


  Weathering and erosion of rocks
• Sediment deposition


  Layers at the bottom of the ocean
• Sedimentary rock formation


  1. Compaction

  2. Cementation
• Metamorphic rock formation


  Heat and pressure on sedimentary rock
• Igneous rock formation


  Melting of metamorphic rock to form magma, then cooling
• Metamorphic rock formation


  Heat and pressure on igneous rock
• The rock cycle takes hundreds of thousands to millions of years
• Rocks can undergo multiple cycles of weathering, erosion, deposition, compaction, cementation, metamorphism, melting, and igneous rock formation
